The TW3972 features a precision tuned, twin circular dual feed, stacked patch element. The signals from the two orthogonal feeds
are combined in a hybrid combiner, amplified in a wide-band LNA, then band-split for narrow filtering in each band and further
amplified prior to recombination at the output. The antenna also has a strong pre-filter to mitigate inter-modulated signal
interference from LTE and other cellular bands.
